Abstract

Monodispersed ca. 30 nm magnetite nanoparticles were synthesized in a 20/80 ethanol–water solution under ultrasonic irradiation. Both the ethanol–water solution and ultrasonic irradiation were important for the synthesis of the monodispersed magnetite nanoparticles. The ethanol–water solvent improved the monodispersibility of the magnetite particles, on the other hand, limited the formation of magnetite under mechanical stirring. The 100% cubic magnetite particles were successfully synthesized in ethanol–water solution under ultrasonic irradiation.
